T 0 all whom it may concern:

Be it known that we, CLARENCE R. NIXON,- lVALTnR B. SWINDELL, Jr., and JOHN L. DUNNOCK, citizens of the United States, re siding at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Carriers for Bottle-Polishing Machines, of which the following is a speci fication.

This invention relates to bottle polishing machines and has special reference to b'ottle carriers for polishing'machines of the type employing a polishing drum against which bottles are held for the polishing operation. 7 a V The most important object of the invention is to provide an improved form of bottle carrier or holder wherein a plurality of holding frames are arranged by novel means to swing alternately into and outof cooperative re ation with a polishing drum, one of the frames passing through the space enclosed by the other and each frame, when out of polishing position, being in position for loading and unloading the bottles.

With the above and other objects in view, as will be hereinafter apparent, the invention consists in general of a novel and improved oscillating bottle carrying mechanism for machines of this type.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a side elevation showing the general construction of a machine embodying this invention.

Figure 2 is a detail section on the line 22 of Figure 1.

Figure 3 is an en arged detail section on the line 3-3 of Figure 2.

In the construction of the invention herein shown it will'be seen that the machine is provided with a suitable frame indicated in general at 10 and that on this frame is mounted a horizontal shaft 11 whereon is a polishing drum 12. At the front of this frame are mounted guide bars 13 for supporting reciprocating rods 14 carrying forwardly projecting arms 15. Journalled'in the arms 15 are two shafts 16 and 17, these shafts being parallel with the axis of the drum 12. At each! end of each of these shafts there is provided a gear 18, these gears meshing directly so that rotation of one of the shafts in one direction causes rotation of the other in the opposite direction. Thus there is a pair of gears on each shaft, it being found that this prevents distortion of the shafts and strengthensthe entire structure. Secured to the inner faces of the gears on the shaft '16 is apair of arms 19 while on the outer faces of the gears on the shaft 17 is a second pair ofarms 20. It

will be obvious that the shaft 16 is closer than the shaft 17 to the drum 12 and that the shaft 16 is slightly below the shaft 17. Thus the arms 19, when the shafts are rotated, are brought into horizontal position and into cooperative relation with the drum, and alined radially with respect to the shaft 17 Also it will be seen that the arms 20 are diametrically disposed tothe shaft 17 so that when these arms are swimg to horizontal position} they occupy the same radial lines as the arms 19 in said position. Each pair of arms is provided with an angle bottle rack 21 having fingers 22 for gripping bottles B. Moreover, on one of the gears on the shaft 17 is an operating handle 23.

The reason of the arms 19 being shorter than the arms 20 and being on the inside of the gears 18, is that the bottle holder frame formed by these arms and the rack 21 will, when the handle 23 is moved from the. position shown in Figure 1 to vertical position, swing through the space bounded by the arms 20 and their rack 21. Thus movement of the handle 23 effects movement of one bottle rack from the horizontal polishing position to vertical loading and unloading position and at the same time moves the other bottle rack in reversed direction so that it is brought into cooperative relation with the drum 12. It will now be understood that during the polishing of one set of bottles the rack for the other set is unloaded and reloaded and as the polishing operation on the first set is finished, the second set is moved to polishing position as the first set moves to unloading and loading position. This operation is continuous until all the desired bottles have been polished.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be desired to confine the invention to the exact form lie-rein shown and described, but it is desired to include all such as properly come within the scope claimed.

Vhat is claimed is 1. In a bottle polishing machine, a polishing drum, a pair of bottle holding frames each mounted to swing toward and from said drum, and gearing connecting said frames and arranged to move one of the frames toward the drum as the other is moved away from the drum.

2. In a bottle polishing machine, a polishing drum, a pair of shafts journalled parallel to the axis of said drum, a pair of arms on each of said shafts, bottle holding members each carried by a respective pair of said arms and a pair of meshing gears each mounted on a respective shaft whereby said shafts are arranged to rotate in opposite directions to bring the bottle holders alternately into operative relation with the drum.

3. In a bottle polishing machine, a polishing drum, a pair of shafts journalled in parallelism to the axis of said drum, one of said shafts being closer to the drum than the other, a pair of gears on one of said shafts adjacent the ends thereof, a second pair of gears on the other shaft meshing with the first pair directly, a pair of arms fixed to the inner faces of the first gears, a second pair of arms fixed to the outer faces of the second pair of gears, each pair of arms being movable between horizontal position in cooperative relation with the drum and Vertical position out of such relation, and bottle sacks each carried by the free ends of a respective pair of arms.

In testimony whereof we afiiX our signatures.
